4 Claims. (01. 126-39) This invention relates to cooking rangeconstruction, and particularly to the fon'n of the gas cooking topwherein the arrangement of the burner controls is grouped in such mannerthat they are readily accessible at a substantially single position atthe front of the range.

A further feature resides in a construction in which, as distinguishedfrom the usual gas manifold which extends entirely across-the front ofthe range, or in some models, just to the rear of and in-which the gasvalves are grouped'in such manner that the valve stems, associated withthe handles at the front, maylie in grouped parallel relation, andextend transversely of the stop beneath the cooking surface, at appro'zie mately the center line thereof.

A further feature resides in the particular ar- 7 rangement of the mixertube arms, whereby they may properly cooperate with the grouparrangement of the gas controlling valves at the rear .of the range.

A further feature resides in the construction wherein the cooking topmay be formed in complete units; that is'to say, a cooking unitmayembodyin a single device, a top surface, or a section thereof, the burner(which is of the converging type, forming the subject matter of acopending application), and the mixer tube arm. The above and many otheradditional features and advantages will become apparent to those'looking in the direction of the arrow 3 in Fig. 1;

Fig. 4 is a front perspective view of a console type range embodyingmyinvention;

Fig. .5 is a front perspective view of a combined coal and gas rangetowhich'my invention may be applied; and

Figs. 7 and 8 are top plan views'similar. to Fig. 1 respectivelydisclosing of theinvention.

Referring more'particularly 't'o'the drawings 10 a front plate, Iprovide a hollow casting arranged at the rear of the range, near thetop,

modified embodiments ures 1 through 4, range, embodying our invention,it being recognized that the construction forming the subject matterthereof may have its application to any of the well known types of rangeor stove now' in use, and certain of which, by way of illustration areshown in the accompanying drawings.

As illustrated in the views in Figs. 1 2 and 3, the idea is shown asapplied for instance, to a console range, such as is shown in Fig. 4,-the invention however, being directed 'to the burner and top structure,irrespective of the peculiar design of stove to which it is adaptablefor use.

In Fig. 2, the low oven is shown at 2, the door therefor at 3, and theinsulated cover at 4, the flue 5, provided by the under sheet of thecover and a spaced plate 6, being for the usual purpose of venting theoven to an outlet (not necessary to be shown) at the rear of the range.The oven door is provided with a suitable handle 8. Thecooking top, isas shown, formed by a pair of combined top plate and burner members)wherein the burners are indicated at I0 and the conduits cast as anintegral part of" the plate structure at H.

'I'hepresent structure, however, departs from the arrangement disclosedin the application re ferred to, to the" extent that while employing thefull idea therein proposed adapts it for use 30 in the peculiar manneras now described. The

- present invention contemplates, as distinguished from the morecommonly known-and used arrangement of gas burner mixer tubes, valvesand v handles. disposed at some portion of the stove at thefront thereofin a. straight line along the manifold, the grouping of both the valvesand their associated elements and also the control handles, the formerpreferably at the rear and the latter at ,the front of the stove.

To this end, I provide each .of the top burne plates l2 having theburner l4 and the cast in gas conduits IS, with a pair of paralleLmixertube arms l6 also preferably cast integral with the burner plate 12, andextending inwardly .in parallel relation with each other, with the rearedge thereof, and terminating in mixer chamber I'M-short of the innerside edge of the plate.

Each of the mixer ,chambers II. is provided with a pivotal air valve,IB. cpntrolling'the air inlet opening l9 5 As shown in Figs. '1 and 2especially, the two top burner plates are arranged with their longerandside edges in parallel relation and in substantial juxtaposition, themixer tube arms of aby numerals of reference, and especially to Figtherespective plates extending in opposite 1.

I indicates the body of the rections inwardly and toward one another,there side with a gas supply pipe 23 which leads to a suitable source ofsupply, not necessary to be.

shown. Mounted upon the top of the manifold box 22 in grouped relationare a plurality of gas valves 24 and 25, the former controlling thepassage of gas to the oven, while the latter control the gas to theseveral burners of the top plate, through the mixer tube arms l6respectively.

As shown in Fig. 2, the several valves 24 and 25, as well as the arms 16are arranged in substantially the same horizontal plane, the valvebodies being supported by studs 26 communicating with the interior ofthe manifold box 22, and the valves being turnable on horizontal axeswhich are in parallel relation. The vertical axes of the several valvesupporting studs 26 define a triangular outline, so that the valves aredisposed in stepped or offset relation, permitting grouping within anarea of small compas's. This is illustrated more clearly in Figure 1,wherein the valve operating rods 21 connected .with the several 'valves,are allowedto lie close to one another in parallel relation, and extendforwardly of the stove beneath theburner plates and into a valve handlecasing 28 mounted upon the upper front central portion of the range.

- The valve handle casing "is preferably of a general dome shape, itsupper curved wall being provided with a plurality of slots 29 and 30with which oscillate the stems 3| of the valve handles 32 and 33. I

The valve operating rods at their forward ends extend through openingsin the front upper frame member and in which they may have their frontbearings, and into the casing 28. On the free end of each of these rodsis mounted one u of the valve stem handles above referred to, the

outer of the rods carrying the handle 32 while the inner one carries thehandle 33. I To permit the arrangement, the dome is of stepped shape asshown in Fig. 1, so that the front valve handles are both forwardly andlaterally offset with respect to the latter.

The rod 21 which controls the oven valve 24,

38 and utility compartment at 39, the latter closed by door 40 havinghandle 4|. The valve control means is shown here generally at 42.

The structure illustrated in Figs. 5 and 6 embodies a combination gasand coal range, show- 3 ing theadaptability of our invention to thistype of cooking apparatus. In the present views, 43 indicates generallythe body of the range, which includes the gas cooking top 44, the coalburner top 45, oven 46, with door 41, firepot 48 with door 49 and thegrouped burner valve control assembly 50. The details of the generalstructure shown in these two figures form the basis of our copendingapplication, Serial No. 189,214, filed February 7, 1938.

In Figs. 7 and 8 are disclosed the adaptation of the invention todifierent arrangements of burners in the cooking top.

Fig, 7 shows the invention in operative association with four burnersdisposed in staggered or ofi-set relation while Fig. 8 shows theinvention in operative association with four burners disposed in astraight line.

Th [structure of Fig. 8 being more nearly alined with the structure ofFig. 1 than is Fig. 7, I

the structure of Fig. 8 will be first described.

As shown, the cooking top includes a pair of longitudinally alined topplates l2a and a single plate l2b parallel with plates' l2a, contiguousthereto, and of a length equal to the combined length of plates l2a.

Each plate I2a supports a pair of burners l4 with all of the burners ina straight line.

The mixer tube arms I6 supported by the op;

which supports a pair of burners l4 with their centers substantially inthe longitudinaI center hne of the plate, whereby the burnersare in staggered relation.

The iyctangular formation of the cooking top is completed by thesupplemental top plates |2d and l2c. I

In this. form of the invention the valves 24 and 25 are operativelyassociated with a manifold 22a which together with the valves isconcealed beneath the plate I211.

The mixer tubes I6 are related to the valves as in Fig. '1 but the tubesare concealed and disposed substantially centrally of the cooking top.The valve operating means are the same as in the structure of. Fig. 1except that the rods 2'! are much shorter.

Thus while three specific burner arrangements are shown with theimproved valve and valve operating arrangement operatively associatedtherewith, it is manifest that the invention is applicable to variousother gas burner arrangements.

What I claim is:

1. In a gas range, a cooking top, a pair of burners arranged at. eachside of the transverse center line ,of the cooking top, a mixer tube armin communication with each of the burners, the

arms gommon to each pair of burners adjacent their free ends beingparallel and in closely spaced relation, with corresponding ones of thetwo pairs of arms being axially alined and with their free ends inspaced relation, a manifold dis posed between the free ends of the arms,valves,

for controlling the flow of gas from the manifold to the arms, valveoperating rods oscillatably mounted beneath the cooking top in closelyspaced parallel relation and in a single horizontal plane, and handlesconnected withthe respective rods disposed at the front of the cookingtop adjacent saidtransverse center line'and movable parallel with thefront of the cooking top for oscillating said valve operating rods, saidvalves being arranged in triangular formation with the apex of thetriangle rearwardly from the front of the cooking top and wherein saidhandles are also arranged in triangular formation with the ape xforwardly of the front of the cooking top for providing compactarrangement of the valve operating rods in parallelism and in a singlehorizontal plane.
